Central communication

unit

OZW775

V3.0

with integrated web server function

The central communication unit OZW775 in plants is used together with Synco

700 devices, RXB/RXL room controllers and the Synco

living central apartment

unit. Key features:

• Remotely operate and monitor up to 250 Synco devices in a KNX network via

ACS and/or via web browser (CD with ACS700 software included in delivery).

• Link to an operator station (PC/laptop with ACS) via direct connection (USB)

or telephony (RS-232 modem).

• Link to a web browser via Ethernet (Ethernet card OZZ7E5 required) and/or

via direct connection or telephony.

• Operation and monitoring via customized plant diagrams.

• Customizable user profiles for web operation.

• Customizable user texts for inputs, outputs, function blocks.

• Send fault status messages to operator stations, SMS recipients,

pagers, fax machines, e-mail recipients (message receivers).

• Periodically send system reports to message receivers.

• Storage of the last 500 faults and messages (history).

• 4 message receivers with configurable receiver types and transmission times.

• 8 digital inputs for fault and operational status contacts.

• 8 universal inputs, configurable for analog, digital and pulse signals.

• 5 runtime totalizer meters, automatically send service alarms.

• 8 meters for pulse signals from heat, water, gas or electricity meters.

• 4 seven-day time switches to switch consumers via relays.

• 6 relays for use with 7-day time switches or as fault relays.

• 5 offline trends with 50,000 recorded values.

Use Buildings • Office and administrative buildings, residential housing. • Schools, gymnasiums, leisure facilities, hotels. • Municipal buildings, industrial buildings. Building operators • Building maintenance companies, facility management. • Real estate agencies. • District heating companies, installers, end customers.

Fault acknowledgement The "Local" LED blinks to indicate that a fault is unacknowledged. The LED continues to be lit until the fault is no longer pending even after the fault is acknowledged with the "Ack" button. "Ack" resets the fault relay if a fault relay is configured. The same applies to unacknowledged "System" faults in the event of a configured fault relay. Without fault relay, a "System" fault is acknowledged automatically, i.e. the "System" LED is lit immediately (no blinking until acknowledged).

Mechanical design The central communication unit consists of the housing lower section with printed circuit boards and connection terminals. The upper housing section contains the printed circuit boards. The LEDs, operating buttons, interfaces, and slots for the CF cards (compact flash memory cards) are integrated in the upper housing section. These elements and the connection terminals are labeled on the front of the housing. The shape and dimensions of the housing sections conform to DIN 43880 (size 2).
PAGE 6
Technical design The central communication unit contains various function blocks (FB). The functionality of the unit can be extended by connecting (binding) the digital inputs N.D1…N.D8 and the universal inputs N.X1…N.X8 to the FB inputs "d", "x", and "i" (see figure and function block description). Inputs and outputs Digital inputs The digital inputs N.D1…N.D8 help connect potential-free status contacts. They act as fault inputs when connecting digital inputs to FB "Faults".
PAGE 7
Function blocks FB "Faults" FB "Faults" is designed for 20 fault inputs. Inputs N.D1…N.D8 (digital) and N.X1…N.X8 (digital/analog) are connected to FB inputs "x". "Relay 1" and/or "Relay 2" is activated depending on fault priority and source. FB "Faults" handles faults and failures of the Synco devices (“System“ faults) listed in the device list as well as faults at the fault inputs and faults of the central communication unit ("Local" faults)..
PAGE 8
Plant diagrams Plant diagrams in the OZW775 V3.0 allow users to display the entire HVAC installation along with all data points. Users can view plant and room states from a user viewpoint, thus gaining a better overview. In the event of faults, access to faulty equipment is much faster. Clicking the diagram opens a dialog box for read/write parameters, allowing users to change values as illustrated below for a change of "Comfort cooling setpoint".

Operation, monitoring, alarming Communication connections for local monitoring and alarming (USB), and for remote operation via modem and Ethernet. Parameter settings for message receivers The following table lists all parameters for the communication connections that can be set in each message receiver.

Commissioning notes Authorized staff Only authorized staff may commission and parameterize the central communication unit as well as start the web server. Select telephone service provider and modem You must select the telephone service provider and modem depending on the message receiver type prior to commissioning. If you use a GSM modem, make sure that the SIM card allows for data communication and that it is not protected by a PIN code.
